A Study to Evaluate the Adverse Events, and Efficacy of Intravenous (IV) of Telisotuzumab Adizutecan in Combination With IV Oxaliplatin, Fluorouracil, Folinic Acid/Leucovorin, Bevacizumab, Panitumumab in Adult Participants With Metastatic Colorectal Cancer

NCT06820463

Recruiting

CRC is the third most common type of cancer diagnosed worldwide with developed countries at highest risk. The purpose of this study is to assess adverse events and change in disease activity when telisotuzumab adizutecan is given in combination with oxaliplatin, fluorouracil (5FU), leucovorin (LV) (FOLFOX), and bevacizumab or panitumumab. Telisotuzumab adizutecan is an investigational drug being developed for the treatment of mCRC. Fluorouracil and leucovorin are drugs approved for the treatment of mCRC. This study will be divided into two stages, with the first stage treating participants with increasing doses of telisotuzumab adizutecan with FOLFOX and bevacizumab or 5FU/LV and panitumumab until the dose reached is tolerable and expected to be efficacious. Participants will then be randomized into 3 groups called treatment arms where one group will receive one of two optimized doses of telisotuzumab adizutecan from the dose escalation phase with FOLFOX and bevacizumab or 5FU/LV and panitumumab, or a comparator of FOLFOX and bevacizumab or panitumumab. Approximately 390 adult participants with mCRC will be enrolled in the study in 100 sites worldwide. In the dose escalation stage participants will be treated with increasing intravenous (IV) doses of telisotuzumab adizutecan with FOLFOX and bevacizumab or 5FU/LV and panitumumab until the dose reached is tolerable and expected to be efficacious. In the dose optimization stage participants will be receive FOLFOX or receive 5FU/LV, but with one of two optimized doses of telisotuzumab adizutecan, or a comparator of FOLFOX and bevacizumab/pantitumumab. The study will run for a duration of approximately 6 years. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and side effects. Read Less

Crohn's Disease: Efficacy, Safety, and Pharmacokinetics of Upadacitinib in Pediatric Subjects With Moderately to Severely Active Crohn's Disease

NCT06332534

Recruiting

Crohn's disease (CD) is a long-lasting disease that causes severe inflammation (redness, swelling), in the digestive tract, most often affecting the bowels. It can cause many different symptoms including abdominal pain, diarrhea, tiredness, and weight loss. This study will assess how safe and effective oral Upadacitinib is in treating moderately to severely active Crohn's Disease in pediatric participants aged 2 to 18 years old who have had inadequate response, loss of response, intolerance, or medical contraindications to corticosteroids, immunosuppressants, and/or biologic therapy. Upadacitinib (RINVOQ) is a drug approved in adults for moderate- to severely active CD and is being developed for moderate- to severely active CD in pediatric participants. This study is conducted in 2 periods: Period 1 is comprised of two phases: a 12-week open-label induction phase which means that the study doctor and participants know that participants will receive UPA Dose-A (or the adult equivalent based on body weight) followed by a 52-week double-blind maintenance phase meaning that neither the participants nor the study doctors will know which dose of upadacitinib will be given(UPA Dose B or Dose C). Period 2 is a 156-week open-label extension of Period 1. Approximately 110 pediatric participants with moderate to severely active CD will be enrolled at approximately 92 sites worldwide. Participants will receive upadacitinib oral tablets once daily or oral solution twice daily at approximately the same time each day, with or without food. Participants will have a safety follow up for 30 days after discontinuation from any time point within the study. There may be higher treatment burden for participants in this trial compared to their standard of care (due to study procedures). Participants will attend regular (weekly, monthly) visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires. Read Less

A Study to Assess Change in Disease Activity and Adverse Events of Oral Upadacitinib in Adult and Adolescent Participants With Moderate to Severe Hidradenitis Suppurativa Who Have Failed Anti-TNF Therapy

NCT05889182

Recruiting

Hidradenitis suppurativa (HS) is an inflammatory skin disease that causes painful lesions in the axilla (underarm), inguinal (groin) and anogenital (anal/genital) regions. This study will assess how safe and effective upadacitinib is in treating adult and adolescent participants with moderate to severe HS who have failed to respond to or are intolerant of anti-tumor necrosis factor (TNF) therapy. Adverse events and change in disease activity will be assessed. Upadacitinib is an approved drug for ulcerative colitis, atopic dermatitis, rheumatoid arthritis, psoriatic arthritis, and axial spondylarthritis and is being developed for the treatment of HS. This study is "double-blinded", meaning that neither the trial participants nor the study doctors will know who will be given upadacitinib and who will be given placebo. This study is comprised of 3 periods. In Period 1, participants are randomized into 2 groups called treatment arms where each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to placebo. In Period 2, participants are placed into 6 different groups depending on their placement and results in Period 1. Period 3 is the long-term extension period where participants will continue treatment from Period 2. Approximately 1328 adult and adolescent participants diagnosed with HS will be enrolled in approximately 300 sites worldwide. Participants will receive oral tablets of upadacitinib or placebo once daily for 36 weeks in Period 1 and Period 2. Eligible participants from Period 1 and Period 2 will enter Period 3 and receive oral tablets of upadacitinib or placebo once daily for 68 weeks. Participants will be followed up for approximately 30 days. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular outpatient visits during the study. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.
